Detachable Power Head

Abstract

A detachable power head (200) and a detachable equipment (500, 900) provided for hand held applications; such as a trimmer, blower, etc. The power head includes an internal combustion engine and a ring on the housing and a matching ring on the power equipment for easy attachment of the power head to the equipment.

Description

BACKGROUND[0001]The present invention relates to hand held equipments in general and lawn and garden equipment in particular. The current equipments, for example, trimmer, blowers, generators, cultivators, water pumps, etc, including go-peds all each have internal combustion engines or electric motors, which are either battery powered or electrical motors. Each equipment powered, particularly by the internal combustion engines more or less are all about the same power ratings and even operate within the same RPM ranges. The disadvantage to the customer is that not all the equipments are used year long and in most cases they are used seasonally. Sometimes, they are rarely used, such as the emergency power generators. As such, the disadvantages are that the consumer has to pay for each engine and have to maintain them regularly, whether the equipment is used or not. Secondly, the equipment typically carry about one to two years warranty, which means the warranty simply expires even if...

AI Technical Summary

Benefits of technology

The power head is an engine that can be used with any type of fuel and can be attached to different equipment. It can be used with a trimmer or a blower as examples. The engine is attached to the equipment with a ring and a matching ring that lock into place, allowing for secure power transmission. The engines can be used with multiple equipment by simply attaching them to the power head. The invention has advantages in that it allows for easy attachment of equipment to the engine and allows for the use of different types of equipment with a single engine.

Problems solved by technology

The disadvantage to the customer is that not all the equipments are used year long and in most cases they are used seasonally.

As such, the disadvantages are that the consumer has to pay for each engine and have to maintain them regularly, whether the equipment is used or not.

Secondly, the equipment typically carry about one to two years warranty, which means the warranty simply expires even if the engine is not used for the reasonable number of hours a year.

Thirdly, each of the equipments mostly likely requires carburetor or fuel treatment for long term storage and annual maintenance.

Also, in most cases, the lubricating oil in each of the engines, has a limited shelf life and need to be periodically changed.

Changing the oil means expense and polluting the environment.

As such, the real life cycle cost of each equipment is unnecessarily higher and wasteful.

This means the older engines keep polluting even though cleaner engines are available in the market.

However, the attachments are not designed for optimum performance and become heavy, particularly when a blower or a cultivator attachment is attached to a trimmer engine having an upper boom.
